Hi, I have a honey do job for this weekend which involves a new acrylic tub installation. I know you need to lay down a mortar bed but we have only one bathroom and would not want to wait all weekend for the regular mortar to set up. So wondering if I can use a quick setting mortar?

I have read up and was wanting to use structolite but unable to get locally and can get plaster of paris but afraid thats too fast for me.

Can anyone recommend me a quick setting mortar or a thinset for this? thanks!!
